10 p.m. update: The Dolphins didn't draft a running back but they added an interesting prospect at the position moments ago when they signed former Oklahoma tailback Damien Williams.

Williams ran for 946 yards (5.4 per carry) and 11 touchdowns as a junior, then ran for 553 (3.9 per carry) and seven TDs last season before being tossed from the Sooners team in late November because of multiple violations of team rules. He's fast and has good receiving skills.

Williams, 5-9, was pursued by seven teams after the draft. He will compete with Daniel Thomas and Mike Gilislee for the third and fourth running back jobs behind Knowshon Moreno and Lamar Miller.

Here's a running list of other undrafted free agents that are signing with the Dolphins or are getting tryouts with the Dolphins at rookie minicamp:

Sounds like this kid needs to get his head out of his a$$ to be successful. Low risk high reward type of signing, but history proves these guys don't change. Maybe he already has a mental disorder and just needs the proper help..
